Hybrid Tomato Variety &#39;H2123&#39;

ABSTRACT

Hybrid tomato variety ‘H2123’ is described. The tomato variety is a ground-culture hybrid processing tomato variety suitable for machine harvest and is adaptable to humid climactic regions such as the Northeastern USA, Portugal and Italy. It is an early variety with resistance to  verticillium  wilt,  fusarium  wilt races 1 and 2, root knot nematode, tomato spotted wilt virus, bacterial speck and moderate tolerance to bacterial spot.

FIELD

This disclosure relates to the field of plant breeding. In particular, this disclosure relates to a new variety of tomato, Solanum lycopersicum variety denominated ‘H2123’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that give an advantage to the grower, processor, consumer, or other members of the supply chain. The improvement may be in the form of field performance, disease resistance, factory performance, or a fruit quality characteristic. For a tomato variety to be suitable to be grown for processing, the variety must have a concentrated fruit setting and maturity, firm fruit, and sufficient rot tolerance to allow early fruit to remain rot-free while later fruit continues to develop and ripen.

Most tomato varieties for commercial processing are hybrids resulting from a cross pollination of two true-breeding, inbred parents. Through the use of true-breeding lines, a hybrid is produced that often displays characteristics of each parent, and often demonstrates characteristics that are superior to either parent alone, or that allow a hybrid to mask inadequacies of the individual parents.

Processing tomato varieties combining resistance to verticillium wilt race 1 (Verticillium dahlia), fusarium wilt races 1 and 2 (Fusarium oxysporum pv lycopersici) and root knot nematode (Meloidogyne incognita) are highly desirable in most climates around the world. Humid growing climates, such as the Northeastern United States have pressure from bacterial and fungal pathogens. Frequent outbreaks of bacterial spot (Xanthomonas spp.), bacterial canker (Clavibacter michiganensis) and early blight (Alternaria solani) can occur. Thus, varieties with resistance are in high demand by both growers and processors to ensure a productive crop cycle.

Processing tomato quality parameters differ from those of fruit used in the fresh market. The processing characteristics are typically determined using a sample of hot-break tomato pulp or juice produced in a consistent manner to those familiar with the art. For example, a fixed mass of tomatoes may be cooked in a microwave oven for several minutes to halt any enzymatic breakdown of the sample, lost water is replaced, and the sample is pulped to remove skins and seed to produce a uniform juice sample. The juice sample can be analyzed for various quality parameters important to processing tomato including but not limited to gross viscosity measures such as juice Bostwick, soluble solids measures using a refractometer (°Brix), measures of acidity and pH, and measures of color (e.g., a Hunter a/b score). The value of these traits depends on the product that is being commercially produced by the processing factory. In some instances, a factory will put a higher value on a thick viscosity variety, whereas in other instances, a thin viscosity will make a superior product and is preferred.

SUMMARY

Provided herein is a new and distinct tomato variety named ‘H2123’ that produces good field yields of medium uniform fruit and is best adapted to humid environments such as the Midwestern US and Italy. The adaptability of ‘H2123’ is enhanced by a relatively short plant cycle, enabling production in growing regions with shorter seasons. The variety ‘H2123’ has resistance to verticillium wilt race 1, fusarium wilt races 1 and 2, root knot nematode, bacterial speck and tomato spotted wilt virus. ‘H2123 has also demonstrated a modest level of tolerance to bacterial spot. The fruit of ‘H2123’ have average red color and an average fruit weight of 69 grams. ‘H2123’ presents an advantage over industry standard varieties such as H1015 by adding resistance to tomato spotted wilt virus coupled with an earlier maturity. Tolerance to fruit rot in ‘H2123’ is excellent, allowing for once-over machine harvesting applications requiring extended field holding.

DETAILED DESCRIPTION

Described herein is the new and distinct tomato variety named ‘H2123’ that was developed to provide a ground-culture hybrid tomato variety (i.e., not grown on stakes) that is suitable for machine harvest and are adaptable to the climactic conditions of regions such as the Northeastern United States.

Processing tomato varieties combining resistance to verticillium wilt race 1 (Verticillium dahlia), fusarium wilt race 1 and 2 (Fusarium oxysporum pv. lycopersici), root knot nematode (Meloidogyne incognita), bacterial spot (Xanthomonas campestris spp.), bacterial canker (Clavibacter michiganensis) and early blight (Alternaria solani) are highly desirable in many humid climates around the world. Varieties for processing are also valued when they are very firm and have a maturity concentrated enough to allow for machine harvesting prior to the onset of fruit rots.

Tomato plants of ‘H2123’ are resistant to verticillium wilt race 1, fusarium wilt races 1 and 2, root knot nematode, bacterial speck and tomato spotted wilt virus. Moderate tolerance is bacterial speck is also a hallmark of the variety ‘H2123’. Plants have a medium-large vine, early maturity and a compact growing habit as compared to tomato varieties of the same market class. Fruit of ‘H2123’ are firm, very smooth, and medium in size (69 grams). Fruit are also considered to have an excellent extended field storage, which delays the onset of fruit rots after reaching red ripe maturity.

Stability of Variety ‘H2123’

The variety is uniform and stable within commercially acceptable limits. As is true with other tomato varieties, a small percentage of variants can occur within commercially acceptable limits for almost any characteristic during the course of repeated multiplication. However, no variants were observed during the three years in which the variety was observed to be uniform and stable.

Comparison of ‘H2123’ to Closest Varieties

Data in Table 1 is based primarily upon trials conducted in Collegeville, California from two replications, non-staked, in a research plot environment among two checks, ‘H1015’ and ‘H3402’. Data in Tables 2, 3, and 4 are based upon observations and laboratory fruit quality measurements made in numerous trials throughout California over a 2-year period, relative to ‘H1015’ and ‘H3402’. Disease resistance and adaptability assessments are based upon DNA markers associated with the disease resistance when available or numerous observations collected in regions/climates with specific disease pressure, specifically for ripe fruit rots, bacterial spot, bacterial canker, early blight, and late blight, including Ontario, Canada.

Several characteristics can distinguish ‘H2123’ from the similar commercial variety ‘H1015’, particularly when compared side-by-side in trials. The two most prominent distinctions between ‘H2123’ and ‘H1015’ are the added resistance to tomato spotted wilt virus, and bacterial spot with ‘H2123’. From a processing standpoint, ‘H2123’ has a lower serum viscosity and higher juice Bostwick than ‘H1015’ making it more suitable for processors seeking thinner viscosity products. Both ‘H2123’ and ‘H3402’ are North Eastern US adapted processing varieties with very good yield. The most prominent distinguishing features between these varieties include the resistance to bacterial spot and tomato spotted wilt virus with ‘H2123’. ‘H2123’ also has a larger fruit size and an earlier cropping maturity, with ‘H2123’ coming in a few days earlier than ‘H3402’. These differences are of significant economic value to processors.

Further Embodiments

Additional methods provided herein include, without limitation, chasing selfs. Chasing selfs involves identifying inbred plants among tomato plants that have been grown from hybrid tomato seed. Once the seed is planted, the inbred plants may be identified and selected due to their decreased vigor relative to the hybrid plants that grow from the hybrid seed. By locating the inbred plants, isolating them from the rest of the plants, and self-pollinating them (i.e., “chasing selfs”), a breeder can obtain an inbred line that is identical to an inbred parent used to produce the hybrid. Accordingly, another aspect of the disclosure relates a method for producing an inbred tomato variety by: planting seed of the tomato variety ‘H2123’; growing plants from the seed; identifying one or more inbred tomato plants; controlling pollination in a manner which preserves homozygosity of the one or more inbred plants; and harvesting resultant seed from the one or more inbred plants. The step of identifying the one or more inbred tomato plants may further include identifying plants with decreased vigor, i.e., plants that appear less robust than plants of the tomato variety ‘H2123’. Tomato plants capable of expressing substantially all of the physiological and morphological characteristics of the parental inbred lines of tomato variety ‘H2123’ include tomato plants obtained by chasing selfs from seed of tomato variety ‘H2123’.

One of ordinary skill in the art will recognize that once a breeder has obtained inbred tomato plants by chasing selfs from seed of tomato variety ‘H2123’, the breeder can then produce new inbred plants such as by sib-pollinating, or by crossing one of the identified inbred tomato plant with a plant of the tomato variety ‘H2123’.

The disclosure further includes introducing one or more desired traits into the tomato variety ‘H2123’. For example, the desired trait may include male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes. The desired trait may be a genetic locus that is a dominant or recessive allele. The genetic locus may be a naturally occurring tomato gene introduced into the genome of a parent of the variety by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques. For a genetic locus introduced through transformation, the genetic locus may comprise one or more transgenes integrated at a single chromosomal location. Accordingly, the disclosure provides tomato plants or parts thereof that have been transformed with one or more transgenes (i.e., a genetic locus comprising a sequence introduced into the genome of a tomato plant by transformation) to provide a desired trait. In one aspect, the one or more transgenes are operably linked to at least one regulatory element. In one aspect, the tomato plant or plant part comprising a transgene has all the physiological and morphological characteristics of tomato variety ‘H2123’.

The gene(s) may be introduced to tomato variety ‘H2123’ through a variety of well-known techniques, including for example, molecular biological, other genetic engineering, or plant breeding techniques, such as recurrent selection, backcrossing, pedigree breeding, molecular marker (Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats (SSRs) (also referred to as Microsatellites)), enhanced selection, genetic marker enhanced selection, and transformation. Accordingly, tomato seed, plants, and parts thereof produced by such genetic engineering or plant breed techniques are also part of the present disclosure.

Also provided herein are single locus converted plants and seeds developed by backcrossing wherein essentially all of the morphological and physiological characteristics of an inbred are recovered in addition to the characteristics conferred by the single locus transferred into the inbred via the backcrossing technique. A single locus may comprise one gene, or in the case of transgenic plants, one or more transgenes integrated into the host genome at a single site (locus). One or more locus conversion traits may be introduced into a single tomato variety. In one aspect, the tomato plant or tomato plant part comprising a single locus conversion has all the physiological and morphological characteristics of tomato variety ‘H2123’.
